FLAT-IRON.

Specification of Letters Patent. Patented Oct. 11, 1910.

Application filed May 27, 1910. Serial No. 563,707.

To all whom it may concern:

Be it known that I, FRITZ JOHNSON, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new anduseful Improvements in Flat-Irons, of which the following is a specification,

reference being had to the accompanying drawing, forming a part thereof.

The main objects of this invention are to provide a flat iron with means within itself or generating steam for moistening clothes I or fabrics elfectively and evenly as they are I actors designate the same parts inthe sevof on the line 2 2,

although it is susceptible of era]. figures.

Figure 1 is a medial vertical longitudinal section of a flat iron embodying the invention; Fig. 2 is a vertical cross section there- 'Fig. 1; and Fig'; 3 is a vertical cross section of the sight-feed water supply connection of the steam generator chamber on the line 3 3, Fig. 1.

Referring to the drawing illustrating the invention as embodied in its preferred form,

various in details ,of construction without departing from the principle and scope of the invention, the flat iron comprises generally a base section a, a burner section b, and a steam generator section 0.

The base section a is formed with a steam chamber d, a number of small perforations e in the bottom communicating with said chamber and an upturned marginal wall The burner section b which corresponds 1n shape with the base section and is removably fitted to the upturned wall 7 thereof, is formed witha gas passage 9 surrounding an opening in the center, jet openings h in the underslde directed downwardly toward the top wall of the steam chamber 03 in the base and an upturned marginal wall 2'.

The steam generator section 0 is formed with a chamber j having an outwardly and downwardl; projecting flange 7c removably fitted upon the upturned wall z'of the burner upper end in a cock sand nip changes section and with flue openings or passages Z leading upwardly through the chamber 7' over the open center of the burner section b.

The flange 1c is formed or provided on the upper side with tubularposts m, the holes oi which register with screw holes in the burner and base sections 6 and a. Upon the posts m is mounted a cover plate or shield 12 a short distance above the top wall of the steam generating chamber j. This plate or shield is formed or provided on the upper side with handle arms or standards 0 between which is fastened a handle grip p of wood or other suitable material.

The several sections of the iron with the Y cover plate are detachably fastened and held together by screws 9 passingloosely through said plate and the upper sections 0 and b and threaded in the holes in the base section a.

The burner is provided, preferably at the rear end of the iron, with a fuel supply connection consisting of an. upturned elbowshaped pipe or fitting 1", terminating at its ple t for the attachment of a rubber or fiexlble tube (not shown) by which it is connected with'a gas 1 e. ifielow thecock s the pipe 1' is provided with inletopenings u to supply the requisite quantity of air for mixture with the gas before it issues from the o enings h.

The wall of the iron is formed below the burner adjacent to the jet openings 72, with inlet openings 1:, to supply' air for the proper combustion of the mixture of gas and air as it issues from the burner openings. Inlet openings w are also formed in the wall of the iron above the burner to afford an addi-- tional and abundant supply ofair to the chamber above the burner in order to insure complete combustion and prevent smoking and an unpleasant odor.

The steam generating chamber j is connected, preferably at the rear end of the iron, with the steam chamber din the base by an enlarged upturned pipe sectlon or the upper end thereof into the chamber d.

The tube 3 is preferably provided with a coupling a for disconnecting the base section a and steam generator section 0 when desired, for any purpose such as cleaning or repairing the iron. v The upturned pipe section or chamber a:

chamber from flowing serves not only as a reservoir for the steam generated in the chamber j, but also to prevent any water which may collect in said into the chamber (2 and out of the perforations e.

Water is supplied to the generator chamher 7' through a si ht feed connection 2, provided with a regulating valve 3, a stop cock 4 and a nipple 5, for the attachment of a rubber or flexible tube (not shown) by which it is connected with a water pipe.

In the operation of the iron, gas being supplied to the burner through the pipe connection 1', is lighted through the opening (shown in Fig. 1) in the wall fat the rear end of the iron, and the jets of flame being directed downwardly from the openings it against the top wall of the chamber d, soon heat the entire base to,=and keep it at, the desired temperature, which is regulated by means of the cock 8. Water being admitted throughthesight feed connection 2 into the.

chamber 9', is converted therein into steam by the heat of the burner below, the productsof combustion passing upwardly through the open center of the burner and the flue openingsZ and keeping the walls of said chamber hot. The steam thus generated passes into and fills the enlarged upwardly extending pipe section or chamber a; from the upper part of which it passes through the tube y into the chamber 03, where it is further heated and dried, issuing therefrom through the perforations e in the bottom of the iron and evenly and effectively moistening the garment, or fabric, as the iron passes over and presses it. The supply of water to the generator chamber may be observed by the operator as it passes through the sight feed connection 2 and is regulated by the adjustment of the valve 3.

By the construction and arrangement of the parts of the iron as shown and described, the heat produced by the burner is most effectively and economically applied to keep the base hot and at the same time to generate steam for moistening garments or fabrics as they are pressed. The separation of the parts of the iron and access to the interior for cleanin and repairing the same are also facilitatef.

I claim:

1. In a flat iron the combination of a chambered and perforated base, a steam generating chamber located above the chambered base and connected therewith by a steam conduit, and a burner interposed between said base and steam generating chamber and adapted to heat the same.

, bottom, a steam generating'chamber located j 2. In a flat. iron the combination of a base having a steam chamber and perforated above the base and connected with the chamber therein by a steam. conduit having an upturned bend extending above the steam generating chamber, and a burner interposed generating sight feed water supply connectionprovided with a regulating valve, and a burner interposed between the base and steam generating chamber and adapted to heat both.

4. In a flat iron the combination of a base having a steam chamber and perforations in the bottom communicating with said chamber, a chambered burner open in the center and having jet openings directed downwardly toward the base, and a steam generating. chamber located above the burner and having a water supply connection and a steam connection with the chamber in the base. I 5. In a flat iron the combination with a chambered base having perforations in the bottom, an open center gas-burner having a fuel su ply connection and jet openings directed downwardly toward the base, and a steam generating chamber located above said burner andhaving flue passages, a water supply connection and a steam connection with the chamber in the base.

6. In a flat iron the combination of a base section having a chambered and perforated bottom, an open center burner section mounted upon said base section and having a fuel supply connection and downwardly directed jet openings on each side of the central opening therein, a chambered steam generating section mounted upon said burner section over the central opening therein and having a water supply connection and a steam connection with the chamber in the base, a cover plate provided with screws detachably securing the several sections together.
